Persistent ST-segment elevation in hypertrophic subaortic stenosis: an unusual repolarization abnormality

This report describes a 69-year-old man who was diagnosed as having ventricular aneurysm because of abnormal Q waves and marked ST-segment elevation that had been observed during a seven-year period. On investigation, he had no aneurysm but did have hypertrophic subaortic stenosis. Hypertrophic subaortic stenosis should be considered in the differential diagnosis of an ECG that is suggestive of ventricular aneurysm.
